3D-Printed Piece Saves My Cuisinart Food Processor

The utopian vision of 3-D printing and communal knowledge sharing came true this week, in one small instance. For years I’ve loved the idea of 3-D printing a replacement component when some plastic bit snaps in a machine I’m using. Especially when the manufacturer doesn’t sell that widget and intends for you to junk and replace the whole thing. But in practice, I’ve not found myself in a situation where that would be viable…

Until this week. Last year my mother upgraded her food processor and handed me down her previous model, a Cuisinart DFP-14 (DFP-14BCN to be precise). The machine had seen years of hard work and at last, the little plastic interlock piece at the nexus of the complicated safety mechanism broke.

I spent maybe 90 minutes last weekend trying to fix it. This involved cutting a reinforcement plate out of scrap plastic, epoxying it on, and mounting it with a machine screw (part of the plastic housing had shattered, too). I had tried my best but it was not going to last. Here’s the kludge fix at the point where I called it quits:

The black plastic layer is my addition. This won’t hold up for long.

DIY non-slip soles for footed pajamas

I’ve handed down a few pairs of cozy footed pajamas between my kids. Along the way the soles lost whatever non-skid properties they had and became very slippery. We got them out this fall to keep my two-year-old cozy. He was cozy … and he slid all over on our slick floors, wiping out a few times. Neither slips nor cold bare feet would do. It was time for DIY non-slip soles.

I outfitted two pairs of Carter’s footie pajamas. Both attempts turned out great:

Try to slide in those!

Materials: I used a discarded bike inner tube that could no longer be patched. If you don’t have one, you might be able to score them from a bike shop or repair co-op. I also used heavy-duty Sashiko thread and needle, but I expect you could do this with any needle and thread.

Sand the bottom of a door that sticks without taking it off its hinges

Problem: a wood bathroom door rubs slightly on the tile of a bathroom floor at the midpoint in its swing, sticking in place. I wanted to sand off the tiniest bit so that it swings free.  But it wasn’t worth removing the door from its hinges.

Solution: get some rough sandpaper (I used 60 grit) and an old magazine. Open a dozen pages of the magazine and lay the sandpaper on top, grit up. (Without the magazine padding I’d be nervous that I’d mar the tile floor). Put this stack at a point in the door’s arc where it swings freely.

Before you start sanding: you want to avoid pulling off any strips from a veneer that may be covering the door’s surface.  To avoid that, first sand the trailing edge of the door (that is, the side that hits last when you’re slamming it into the sandpaper), so it isn’t caught and pulled while you slam.  Also consider using a finer grit of sandpaper, which would add a few minutes to the sanding, and opening-and-closing on the sandpaper with less force.  Keep an eye on the veneer throughout the process.

Now, slam the door into the paper stack so that it sticks. In the process, it sands exactly the lowest point on the bottom of the door. Keep swinging it back and forth, slamming it into the sandpaper. As you make progress in shaving the door, you may need to add pages to the stack or move it closer to the point where the door sticks.

Test periodically. In a few minutes you’ve removed a millimeter or two from the bottom of the door and it should swing freely, without altering the look of the door or needing to remove it.

Besides the convenience of this solution, I enjoy its elegance: by replicating the act of making contact with the floor it shaves the door in precisely the right place.

Mending knee holes with sashiko

I love repairing things. For several years I’ve hoped to take up sewing to extend my fixing skills to clothing. Sheltering-in-place during COVID-19 has provided opportunities to try my hand at mending ripped knees in my family members’ pants. It feels good to sit in peace and make something whole again. Apparently I’m part of a trend, with mending and in particular visible mending gaining in popularity.

I asked my friend Cassie where to start in mending holes in knees and she pointed me to the book Mending Life, which had steps that were thorough, clear, and seemed doable – with handy illustrations (pp. 96-103). So I took a shot at it. So far I’m 3 of 3! None are perfect but all three exceeded my expectations. Below are photos.

Specifically, I have been trying to emulate sashiko, a Japanese decorative reinforcement stitching technique. I sewed the first patch with a piece of thick thread I found in my sewing box. The next two I did with proper sashiko needles and thread I ordered online. (As with most of my things, if you live near me and want to borrow them, just ask).

I chose contrasting thread and patches to emphasize the repair jobs. I’m proud of my work, it normalizes repair and reuse, and frankly I think the unique & visible mends leave the clothing looking better than it did new.

Sashiko patch #1: women’s jeans

The ripped fabric at the knee was exploding outwards. It was begging to be patched with the “exposed edge technique” (Mending Life), with an interesting pattern poking through.

Drilling through a broken zipper slider and adding a paperclip pull

The slider on my zipper – in this case, on a waterproof bag for holding soiled cloth diapers – broke such that the top of the bridge separated from the slider body. I tried to glue it to no avail.

Two tailors told me they’d need to replace the entire 16″ run of zipper and quoted me $25 and $26. I could get a new bag for that much. So I took a shot at repairing it.

I drilled through the side of the slider bridge, using a 1/16″ bit. I first used a hammer & nail to make a tiny indentation so the bit wouldn’t walk. If the hole is even a little off-center, it will leave a thin border prone to breaking.

I drilled that hole. Like usual, I forgot to take a “before” picture. It looked like any zipper.

Then I stripped a spare piece of 22 AWG wire I had lying around, bending the copper into a loop. Kind of pretty, I think!

It took just a few minutes and seems to slide well. We’ll see how it holds up.

UPDATE May 2020: the twisted wire was impractical and failed quickly. It has been replaced by a paperclip, which is working much better. The clip falls off in the washing machine, which might pose a risk to the machine. I now remove it before tossing the bag into the wash and reattach afterward. Overall the bag now works as well as new!

Watch repair: metal spring bar tore a channel in a Casio G-Shock end piece

For Hanukkah 2008, I received a new watch from my wife. (I don’t remember the watch before that). It was particularly magical in my job as a high school teacher. After the first bell of the day rang, it was 4 minutes to the start of school, then 46 minutes per period alternating with a 4-minute passing period. Like clockwork, so to speak.

The watch had a auto-repeating countdown timer that I set for 50 minutes and would almost always successfully synchronize with the day’s first bell. That would mean that at any point during the day I could look down and see precisely how many seconds were left in a class or passing period. I could walk the hallways and announce “27 seconds!” or count down “5-4-3-2-1” and then the bell would ring, with me the only person in the school who had that level of precision. There’s probably something there for another post but I digress.

After years of daily wear and companionship, I received a smartwatch as a gift and stopped wearing the digital watch. Then I went from the FitBit to a Basis and then a Garmin. At one point I realized I’d fallen into a consumerism trap and sought to go back. The notifications were disruptive and the data I was generating was useless to me but creepy in the hands of Big Tech. I tried to go back to the Casio, but it had a problem. (Remember the torn-out spring bar in the page title? This post is about the torn-out spring bar).

Each strap is attached to the end piece / bezel by a spring bar. In the course of replacing a broken band and with wear and tear over time, the spring bar on one strap carved a channel from the hole it sits in. With slight force, the strap would pull the pin out through the channel and detach from the bezel. (If this post wasn’t an afterthought I’d have a “before” picture). This person appears to have the same problem, though they too did not post a picture.
